The two MTA -> VMSMAIL (MUA) situations I'm familiar with are vanilla JNET and JNET with PMDF. JNET just uses the 822-From: to create the VMSMAIL-From:. PMDF uses Reply-To:/From:/Sender: in that order (if present). I prefer the PMDF approach since it lets me "answer" to the right person. Others prefer the JNET approach because they like to see originated the message on a DIR of their mail. ---------- Mark J Strawcutter BitNet: MJSTRAW@IUP Director, Systems and Data Communications DNS (mx): [log in to unmask] Indiana University of Pennsylvania Phone: (412) 357-4000 Indiana, PA 15705 "you can't nail jello to a tree"
